ABSTRACT
I would like to close this book by making three comments that re§ect the overall spirit of the proposals made. Že ¨rst thing I want to emphasize is that when one makes a selection
of a light source to be used in a speci¨c area, many parameters must be taken into account such as the tasks performed in that area, the age of people occupying the area, the illuminance levels required, any medical conditions of the occupants, the overall cost, that might or might not be attainable, etc. Že proposals made here covered general cases unless otherwise stated, and the focus was mainly on the spectral outputs of the light sources. It is my ¨rm belief, however, that once the principles on which the proposals are based are taken into account, then any situation can be evaluated and the right selection of light sources can be made.
